Refracting white light into a visible rainbow spectrum

Two independent output channels on this compact AC/DC power supply deliver six selectable voltages up to 12V at 500 mA each

and amphibian skeletal structure for comparative vertebrate teaching

sized so a class can watch gas bubbles rise off each electrode in real time during electrolysis demos

supplying both current types to a single workstation for circuits and electromagnetism
